Severance is a Statutory Town in Weld County, Colorado, United States. The population was 597 at the 2000 census. The town is located on the Colorado Eastern Plains, northwest of Greeley, a crossroads of county roads. Founded in the late 19th century as an agricultural community, the town remained primarily a small rural farming community based on the raising of cattle, sugar beets, potatoes, and onions. In the 1990s it began to grow aggressively by the construction of new residential subdivisions in the nearby rural areas of Weld County, especially as growth spilled over from nearby Windsor. The construction of new residential communities near the town has left the original agricultural community surrounded by modern construction and contributed to an upsurge in population. The town limits, extended through flagpole annexations, reach in tendrils nearly to Windsor and Fort Collins. Since the economic base of the town is quite limited, many of the new residents commute to jobs in Greeley, Fort Collins, Windsor, and even to Denver.
